2 Claims. (Cl. 1'251-164) The. present invention relates to valves and is more particularly concerned with a manually operated valve to be interposed in a Water or gas conduit and the like.

The primary object of the invention is to provide a device of the character referred to which is simple to construct and contains few cast elements.

Another object of the invention is to provide a valve which will be durable when used in a water conduit.

A further object of the invention is to provide a valve which can be readily installed and is of simpler and more compact construction than prior devices.

With the foregoing and other objects and advantages in view, the invention consists of the novel construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawing illustrating the invention:

Figure 1 is a longitudinal section of the invention.

Figure 2 is an end elevation thereof.

Figure 3 is a top plan view.

Like numerals are used in the description and drawing to designate the same parts of construction.

l is the valve case which is preferably a section of pipe or a cylindrical body 2 having enlarged or flared ends 3, threaded interiorly, as at 4, for pipe coupling purposes. Exteriorly the flared ends are formed with facets or wrench surfaces 5 to facilitate connection of the valve case and the threaded ends of pipes serving as conduits for water, gas and the like.

A cylindrical chamber 6 is formed longitudinally in said case and extends from end to end, approximately. This chamber serves as a valve cylinder for a cylindrical valve 1 and is provided with a port 8. A bailie 2a is located inside case I adjacent its outlet and between same and said port to divert the flow into the port. The inner wall of the baflle is curved to facilitate the passage of water or gas without agitating it. Chamber 6 has an open end which projects through the baffle. The cylindrical valve 1 and the interior wall of valve cylinder 6 are both highly polished with a finish similar to that common to pistons and cylinders of motor cars and the like. To this end, the cylinder 6 is bored and polished as in the case of combustion engine blocks. The length of the valve approximates the distance from the port 8 to the closed end 9 of the valve cylinder. The opposite or open end l ll, ofjsam'e, provides the outlet orpassageway from the valve case' proper, through :the po'r t 8. The valve is manually operated by means of a laterally disposed rod or bolt l l, threaded therein at a suitable distance from its innermost end, and projecting outside the valve case through a longitudinal slot l2 in the body thereof. By sliding the bolt II as desired, the valve can be moved in either direction as much as required for either a full or partial opening of port 8, thus regulating the volume of flow.

The projecting portion of the bolt is contained in a lock member l3, which is provided with an open, cylindrical bore 14 designed to hold an helical spring I 5. The spring is confined between an annular shoulder near the bottom of the lock member and a shoulder underneath the head l6 of bolt H.

The foot of the lock element I3 is cross cut to form two jaws I! which are designed to normall engage the notches or spaces formed by parallel ribs Is on the outer surface of the case I adjacent the slot l2. These ribs are disposed transversely of the case, thus forming a rack bar along which the lock member may be moved, when lifted, and secured when lowered. This construction facilitates longitudinal adjustment of the piston within the limits of slot l2. To permit the lifting of the lock member, it is provided at the top with a flanged enlargement l9, within which is an annular recess 20 which allows reciprocatory movement of the lock member on bolt II and its head. By placing ones fingers under the flange on the lock member and thumb on head of bolt, the member can be lifted out of engagement with the said notches. When moved to a new or adjusted position, the lock member is lowered into engagement with the notches,

thus securely locking the piston in the desired position.

The lock member is preferably stamped while the casing I and piston block are cast as a unit and then bored for the valve cylinder 6. As this valve is moved infrequently in the case of a water conduit, the wear is infiinitely less than that on the piston and cylinder of a combustion engine, thus reducing the possibility of a leak to a minimum. This will obviate frequent replacement of parts as in most valves. When wear warrants regrinding of the cylinder 6 it may be done readily through the open end thereof.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

1. A valve comprising a section of pipe threaded at each end for coupling purposes and provided interiorly with a baflle, an ancillary cylindrical chamber located within said section of pipe and provided with an open end extending through the bafile, a port in the longitudinal wall of said chamber adjacent the inner surface of the bafile, a slidahle piston-like valve in said chamber, positioned to serve as a closure for said port, means secured to said valve and extending exteriorly of the valve case through a longitudinal slot therein for operating said valve, and an adjustable member attached to said valve operating means for locking same in various posi tions in said slot.

2. A valve comprising a case having interiorlv threaded annular ends, a bathe in said case provided with a curved inner wall, an integral ancillary valve cylinder positioned longitudinally Within said case and provided with an open end extending through the baflle, a communicating port between the ancillary valve chamber and the main chamber of the case and adjacent the inner surface of the baflle, a slidable piston-like valve in said valve chamber positioned to serve as a closure for said port, a longitudinal slot between said ancillary chamber and the exterior of said case, a removable bolt secured to said valve and projecting exteriorly of the case through said slot, a plurality of recesses on the exterior of the case contiguous to said slot, and a spring-controlled reciprocatory locking member mounted on said bolt and provided with an element to engage said recesses.
